SPRING FOR WAGON -SEATS.

SPECIFICATION forming part of Letters Patent No. 376,718, dated January17, 1888.

Application filed July'i), 1886. Serial No. 207,615. (Njo model.)

To aZZ whom it may concern.-

Be it known that 1, JOHN F. MOORE, a citizen of the United Statesof'A'merica, residing at Centralia, in the county of Wood andState ofWisconsin, have invented certain new and useful Improvements in Springsfor Wagon- Seats, of which the following is a specification, referencebeing had therein to the accompany- -ing drawings.

My invention is a spring-bearer, more especially adapted to'the springsof wagonseats, and embraces, in brief, the following novel features; ahalf-elliptic spring-body having an intermedial and counter-arched.spring-seat and a pair of counter-lugs upon the extremity of eachspring-bearing arm, all of which and their purposes are hereinafter morefully described, and illustrated by the accompanying drawings, in whichlike letters designate identical parts of said invention in'thedifferent figures, respectively.

Figure 1 is a side'view of said device, show:

' ing said counterarched spring-seat, the oppositely-curving shouldersof the bearing-arms, and said securing pairs of counter-lugs-at theextremities of the same. Fig. 2 is an under view of said device. Fig. 3is another side view of said device,'showing the wagon-seatspring-bolted into its counter-arched springseat, and the said pairs ofcounter-lugs at the outer ends of. said spring-bearing arms overlappingthe top edge of the sectional portion of 'a wagon-body side; and Fig. 4is a crosssection of one sideof a wagon-body, and shows an end View ofsaid spring-bearer securely resting upon said body-side.

The letter A represents said spring-bearer, which is made preferably ofmalleable or droppressed spring metal "andtof the general shape shown.The springy armsd rise toward their curved shoulders I) sufficiently toprevent the gravity of any superincumbeut body on the Wagon-seat topress said bearer-spring down upon the top edge of the wagon-body B, andare provided with the counter-arching spring-seat c,'into which thewagon-seat spring Ois firmly bolted, as shown. At the extremity of eachsaid arm of the bearing-spring are formed a duplicate pair of rigidlyand downwardly proj'ecting'connter-lu gs, d, which are made to freelyoverlap the top edges of the opposite vertical sides of the wagon-bod y,as shown,and thereby secure the wagon-seat safely in place, and at,thesame time allow for the proper extension and retraction of saidbearing-spring ends, whilecounter-springing to the motion of the movingwagon and its loaded seat-spring,

hence said device affordsa safe and donblyspringy seat upon the wagonand an extremely compensative and protective elasticity to the;

resiliency of the wagon-seat spring, especially if said seat is occupiedby very heavy weights riding over a very rough road. Said device alsoforms a very readily and economically made and useful article ofmanufacture.

I am aware, lation to wagonseat springs, that said vehiclesprings havemore or less immediate support from the state of the art in reandsecurity from the adjustablyhooking or riding brackets or risers towhich they are bolted or by which they are rigidly clamped; but I amnotaware, said art disclose, that any of said risers or brackets exhibitany elastic or springy quality, or were ever intendedto subserve suchquality,

neither does the history of. J

or were ever made of any such material as ever did or could produce theresults of an extremely compensative and protective spring-seat'for awagonseat spring. 3

Therefore, what I laimasnew, and desire to secure by Letters Patent, is't The bearer of a wagon-seat spring, consisting-of a semi-ellipticalspring-body havingthe counter-arched spring-seat, elastic arms, and

the duplicate pairs of counter-facing, overlapping, andcompensatively-sliding arm-lugs, substantially as and for the purposesherein specified. e In'testimony whereof I affiX my signature inpresence of two witnesses.
